SUMMARY: mount nfs fs fails

2007-12-24 20:15:00

A:

funny but, another sad commentary on firewall admins.
solution "some tcp and udp services needed to be
defined on the firewall to allow for the traffic to be
sent. The reason it took a few tries was to determine
exactly what ports were needed and what could be
excluded from the rule."

sorry for the long post and the quick answer.
